<p><a class="reference external" href="https://ivre.rocks/">IVRE</a> (French: <em>Instrument de veille sur les
réseaux extérieurs</em>) or DRUNK (Dynamic Recon of UNKnown networks) is
an open-source framework for network recon, written in Python. It
relies on powerful open-source tools to gather intelligence from the
network, actively or passively.</p>
<p>It aims at leveraging network captures and scans to let you understand
how a network works. It is useful for pentests &amp; red-teaming, incident
response, monitoring, etc.</p>

<h2>Use-cases<a class="headerlink" href="#use-cases" title="Link to this heading"></a></h2>
<p>IVRE can prove useful in several different scenarios (you may want to
have a look at the <a class="reference internal" href="overview/screenshots.html#screenshots-gallery"><span class="std std-ref">Screenshots gallery</span></a>). Here are
some examples:</p>
<ul>
<li><p>Create your own Shodan-like service, using Nmap and/or Masscan
and/or Zmap / Zgrab / Zgrab2, against the whole Internet or your own
networks, (private or not).</p></li>
<li><p>Store each X509 certificate seen in SSL/TLS connections, SSH public
keys and algorithms, DNS answers, HTTP headers (<code class="docutils literal notranslate"><span class="pre">Server</span></code>,
<code class="docutils literal notranslate"><span class="pre">Host</span></code>, <code class="docutils literal notranslate"><span class="pre">User-Agent</span></code>, etc.), and more… This can be useful to:</p>
<blockquote>
<div><ul class="simple">
<li><p>Validate X509 certificates independently from the clients.</p></li>
<li><p>Monitor phishing domains (based on DNS answers, HTTP <code class="docutils literal notranslate"><span class="pre">Host</span></code>
headers, X509 certificates) hit from your corporate network.</p></li>
<li><p>Run your own, private (or not) <a class="reference external" href="http://www.enyo.de/fw/software/dnslogger/first2005-paper.pdf">passive DNS</a>
service.</p></li>
</ul>

<h2>Getting started<a class="headerlink" href="#getting-started" title="Link to this heading"></a></h2>
<p>If you want to learn more about the different purposes of IVRE, you
should start reading the <a class="reference internal" href="overview/principles.html#principles"><span class="std std-ref">Principles</span></a>.</p>
<p>After that, you can start the <a class="reference internal" href="install/index.html#installation"><span class="std std-ref">Installation</span></a>
process.</p>
<p>Once you are ready, dive into the “Usage” section!</p>

<section id="contributing">
<h2>Contributing<a class="headerlink" href="#contributing" title="Link to this heading"></a></h2>
<p>Code contributions (pull-requests) are of course welcome!</p>
<p>The project needs scan results and capture files that can be provided as
examples. If you can contribute some samples, or if you want to
contribute some samples and would need some help to do so, or if you can
provide a server to run scans, please contact the author.</p>
